A personal story from our own Registered Dietitian Nutritionist, Jacque Maldonado, an accomplished triathlete with five Full Ironman finishes, a dozen Half Ironman finishes, and 7 podium awards.
In training for my first Full Ironman, I made some mistakes with my own nutrition, despite having two degrees in nutrition and 15 years of experience running full marathons. If I can make mistakes, anyone can. The main issue for me was not eating enough. The main issue for you might be something different. I followed a balanced diet, honored my hunger and was hoping to ‘stay lean’, as I didn’t want to carry excess weight for 140.6 miles. However, in not meeting my true energy and protein needs for training, I became amenorrheic and my immune system took a hit. I ended up succumbing to giardia on a backpacking trip a month before my race. Getting sick before a race you have been training hard for is very frustrating. I rested, treated the condition and luckily bounced back. My race was a success because I followed a practiced and well thought out race day nutrition plan. I continued to refine my nutrition skills and got stronger, faster and wiser in subsequent Ironman races.
